摘　　要：运用群落的组成结构、时间结构和营养结构3个方面,系统阐述分析转基因741杨对节肢动物群落结构的影响。研究表明,组成结构上,高抗Pb29和CK节肢动物群落主要组成类群均是鞘翅目、鳞翅目、同翅目、蜘蛛目、膜翅目;营养结构中,与CK相比高抗Pb29节肢动物群落中顶位物种中寄生性天敌数量下降其他则无显著变化,中位物种比例上升,基位物种个体数量下降,主要为食叶害虫中目标害虫的减少,功能团组成类似;时间结构中,高抗Pb29和CK节肢动物群落的物种丰富度和个体数量变化相似;功能团和各个营养层的物种数和个体数均表现出了相近的变化规律。The arthropod community of transgenic 741 poplar was analyzed from three aspects of community structure,temporal structure and nutritional structure.The results show that：on compositive structure,main compositive groups of the community structure were Coleoptera、 LepidopteraAraneae, Homoptera and Hymenoptera in Pb29 and CK;On nutrition strcture,function groups on every nutrition level were similar between Pb29 and CK,but in Pb29leaf-eating pest on bascal species largely decreased,the rate of intermediate species increase,top species have no obviously changing;on temporal structure,numbers of individual and species of Lepidoptera in Pb29 and CK has similarly changing tendency,function groups and every nutritionalasses with individual numbers and species,there have similarly changing tendency.
